Abstract
An electric power generator driven by a fluid circulating under pressure in a pipe (9) includes an internal moving contact (1) placed inside a non-magnetic section (10) of the pipe (9), and a stator (4) placed around the pipe (9). The internal moving contact (1) includes permanent magnets (2), a rotational drive means (3), and means (7 and 8) of support. The electric power generator does not require any sealed joints for the passage of mechanical shafts or electric cables and is particularly adapted for the production of electricity from dangerous fluids which circulate in pipes under high pressure. The electric power generator has application in gas and liquid transport networks, particularly at isolated hydrocarbon production sites.
